Portrait of Kartik Khosa

Kartik Khosa

I’m a software engineer at Microsoft Core AI, where I build the agentic workflows that automate .NET migrations in GitHub Copilot. Before that I spent three and a half years modernizing The Arabidopsis Information Resource and MorphoBank, and I still build open-source tools for evolutionary biology.

My career as a cladogram, drawn the way OpenClade draws trees.

Experience

  1. Apr 2026 – now Current

    Software engineer, Microsoft Core AI

    Redmond, Washington

    • Agentic .NET migration engine. Engineered hybrid C# agentic workflows powering the official GitHub Copilot app, orchestrating Roslyn static code analysis and LLM synthesis across a three-stage engine (assessment, planning, execution) to automate end-to-end .NET Framework migrations, reducing manual effort by 90%.
    • Enterprise modernization at scale. Partnered with .NET experts to build modular upgrade plugins, accelerating multi-year first-party .NET Core migrations, saving years of developer effort and on track to eliminate millions of continuous CPU cores.
    • Autonomous bug triage agent. Developed an autonomous bug triage agent for Azure Storage Explorer using a stateful directed graph loop: GitHub issue ingestion, reproduction script synthesis, defect localization, unit test generation and pull request delivery with root-cause provenance. It resolved 85% of issues.
    • Industry leadership. This work contributes to Microsoft’s position as a Leader in the Gartner Magic Quadrant for AI-Augmented Code Modernization Tools (August 2026).

  2. Oct 2022 – Apr 2026

    Full stack software engineer, Phoenix Bioinformatics

    The Arabidopsis Information Resource (TAIR) and MorphoBank

    • Search architecture. Architected a Spring Boot pipeline replacing SQL queries with S3 JSON data indexed in Solr, cutting search times from 60 seconds to 300 milliseconds.
    • AI summaries. Led development of a LangGraph agent architecture that generates bioinformatics summaries for more than 50,000 locus pages, with section-based summarization, combination, validation and evaluation layers, powered by Gemini 2.5 Flash.
    • Automation. Automated reporting workflows with Spring Boot APIs, dynamic data aggregation and AWS SES, saving business teams more than 1,000 hours a year.
    • DevOps. Built a Docker-based CI/CD platform (Jenkins and GitHub Actions), speeding up releases and greatly reducing rollbacks.
    • Microservices. Designed RESTful Node.js microservices to modernize the Arabidopsis.org backend.
    • Research. Co-authored peer-reviewed papers in Genetics and presented at ISMB 2024 on scalable bioinformatics architecture.

  3. Feb 2020 – Oct 2022

    Solution engineer, Appian Corporation

    • Security and scale. Managed authentication protocols (SAML, OAuth, LDAP) for more than 100 businesses serving over 100,000 users.
    • Code quality. Assessed and optimized more than 25 custom Java plugins against company standards.
    • Documentation. Wrote internal documentation that cut resolution times by 80% across more than 10 customer cases.
    • Client success. Achieved a 95% “very satisfied” rating from clients through technical consultation.

Projects

  1. 2026

    OpenClade

    Phylogenetic analysis of morphological data in the browser

    Parsimony analysis of morphological character matrices that runs entirely in the browser, with no installation and no data upload. It reads NEXUS and TNT files, including MorphoBank exports, handles inapplicable characters with the Brazeau, Guillerme and Smith (2019) algorithm, and produces most parsimonious trees, consensus trees, bootstrap support, character mapping and a methods paragraph. One click shows which clades depend on how inapplicable characters are treated.

    Tree lengths match TreeSearch on all 806 test trees across 31 published matrices, and the search found the exact optimum in 124 of 124 exhaustive tests.

About

I live in Bellevue, Washington. Outside work I never miss a Formula 1 race weekend, I go skydiving and scuba diving when I can, I play Valorant competitively, and I’m always looking for a new place to eat.

I try to bring the same curiosity I have for those things to my work, whether I’m optimizing a system, improving an interface or building something new.
